A Rainy Period...

Another storm system is impacting the Rockies already this evening, likely to bring snowfall amounts greater than a foot in many areas along the foothills in Colorado. A low pressure system will also be created that will quickly move out onto the Plains states and establish itself by tomorrow morning. A stationary front will be draped from southwest Oklahoma to the northeast across Oklahoma, Kansas and into northern Missouri by tomorrow morning. We'll see widespread rain showers by tomorrow morning over central Kansas into southeast Nebraska and southwest Iowa with these areas being just north of the stationary boundary. As the low pressure system continues slowly eastward and the upper level low dig onto the Plains this stationary boundary will slide to the south. Leaving much of Kansas, northern Missouri, southern Iowa and parts of southeast Nebraska in a favorable location for widespread rain showers through the day on Wednesday. This feature will slide eastward during the overnight hours, with additional rain showers and thunderstorms occurring over parts of Oklahoma and Texas. These thunderstorms will work northeast along with the surface low pressure system, making their way into southern Missouri for Wednesday night. Despite the strengthening system at all levels, the storm system will be picked up by an upper level jet streak which will thankfully move this system out of the Plains by Thursday night. Although much of Missouri and adjacent areas will be left under frequent showers and cloud cover through Thursday, the Plains will be dry by dawn on Friday.

We won't have too long to dry out though, as the next storm system will make its' way off of the Rockies and into the Plains by Saturday. This will travel across the Plains over the weekend, and unfortunately with some northern stream energy to work with it will likely feature a decent cold front that will sweep across the area. This will likely lead to a couple of days of below average temperatures, which really is nothing new for the way this year has gone. Luckily the upper level ridge looks to build quickly which will allow the temperatures to rise quickly back to normal and potentially above normal levels for much of next week.

So to recap, two low pressure systems coming off of the Rockies look to affect the Plains states. The first of which for Wednesday and Thursday will bring steady rains and isolated thunderstorms. Perhaps some severe weather with a marginal setup over parts of Texas and Oklahoma. We'll take a day to dry off on Friday before the next system brings more steady rain, becoming a cold rain late, for the weekend. Despite a day or two of chilly temperatures, we'll be quick to warm back up come next week...
